It is a C. maxima of some sort. I can't see any distinguishing features to be able to name the variety. Do you have any idea of what it could be? If you planted this pumpkin and you know what seeds you had I am sure I could narrow it down.

It from a bird drop or something!

It just start growing, i know it some time of squash or zuchini type!

I can't identify the plant, but I'm hoping I identified a poster who was trying to share a link with me elsewhere! ;-)

If not, then just ignore this post!
